* The Inhibit (Disable) Switch overrides the Manual Regeneration Switch. For Manual Regeneration to occur, the Inhibit (Disable) Switch must be in the Not Inhibited (Not Disabled) position. For automatic regeneration the Inhibit (Disable) Switch must be in the Not Inhibited (Not Disabled) position and Manual Regeneration Switches must be in the Automatic position.
